When will gas stations start truly accommodating trailers?

I think most gas station owners make the best of the land that have to deal with. It's not just trailers, even with my short mh some places are hard to get into or just can't. I'm sure it's a thought process they go through to determine how many pumps/island they can get to serve the most people with the least amount of waiting/backup. One of the fallouts may be not being able to serve the larger/longer units.
